<h2 id="intro-ref" class="docs">Introduction to bibliographies and references</h2>

<p>
Mom provides the ability to format and generate bibliographies, as
well as footnote or endnote references, in MLA (Modern Language
Association) style.  She accomplishes this by working in conjunction
with a special groff program called <kbd>refer</kbd>.
</p>

<p>
<kbd>Refer</kbd> requires first that you create a database of works
that will be cited in your documents.  Once that&#8217;s done, special
macros let you briefly key in references to entries in the database
and have mom format them with respect to order, punctuation and
italicization in footnotes, endnotes, or a full bibliography.
</p>

<p>
<kbd>Refer</kbd> has been around for a long time.  It&#8217;s
powerful and has many, many features.  Unfortunately, the manpage
(<kbd>man&nbsp;refer</kbd>), while complete and accurate, is
dense and not a good introduction.  (It&#8217;s a classic manpage
Catch-22: the manpage is useful only after you know how to use the
program.)
</p>

<p>
In order to get mom users up and running with <kbd>refer</kbd>,
this section of mom&#8217;s documentation focuses exclusively, in a
recipe-like manner, on what you need to know to use <kbd>refer</kbd>
satisfactorily in conjunction with mom.  The instructions are not to
be taken as a manual on full <kbd>refer</kbd> usage.
</p>

<p>
If you&#8217;re already a <kbd>refer</kbd> user, the information
herein will be useful for adapting your current <kbd>refer</kbd>
usage to mom&#8217;s way of doing things.  If you&#8217;ve never
used <kbd>refer</kbd>, the information is essential, and, in many
cases, may be all you need.
</p>

<p>
I encourage anyone interested in what MLA style looks
like&mdash;and, by extension, how your bibliographies and references
will look after mom formats them&mdash;to check out

<h4 id="db-ref" class="docs">1. Create a refer database</h4>

<p>
The first step in using <kbd>refer</kbd> with mom is creating a
database.  The database is a text file containing entries for the
works you will be citing.  You may set up separate databases for
individual documents, or create a large database that can be
accessed by many documents.
</p>

<p>
Entries (&#8220;records&#8221; in refer-speak) in the database
are separated from each other by a single, blank line.  The records
themselves are composed of single lines (&#8220;fields&#8221;) with
no blank lines between them.  Each field begins with a percent
sign and a single letter (the &quot;field identifier&quot;)
e.g., <kbd>%A</kbd> or <kbd>%T</kbd>.  The letter identifies
what part of a bibliographic entry the field refers to: Author,
Title, Publisher, Date, etc.  After the field identifier comes
a single space, followed by the information appropriate to
field.
</p>

<!-- Add rules for punctuation and italics -->

<p>
Here&#8217;s an example database containing two records so you can
visualize what the above paragraph says.
</p>

<div id="example-refer-database" class="examples" style="margin-top: -.5em;">Example <kbd>refer</kbd> database</div>

</span>
</div>

<p>
The order in which you enter fields doesn&#8217;t matter.
<kbd>Refer</kbd> will re-arrange them for you.
</p>

<h4 id="rcommands-ref" class="docs">2. Insert a refer block</h4>

<p>
Having set up your database, you now need to put some
<kbd>refer</kbd>-specific commands in your mom file.
</p>

<p>
<kbd>Refer</kbd> commands are introduced by a single line
containing <kbd>.R1</kbd>, and concluded with a single line
containing <kbd>.R2</kbd>.  What goes between the <kbd>.R1</kbd>
and <kbd>.R2</kbd> lines is called a &#8220;refer block&#8221;.
<kbd>Refer</kbd> commands in a refer block should be entered one per
line, in lowercase letters, <i>with no initial period</i> (dot).
The actual commands depend on whether you want your references
</p>
<ul>
<li>in footnotes/endnotes</li>
<li>parenthetically inserted (in abbreviated form) into running text,
referring to a works-cited list (bibliography)</li>
<li>to generate a comprehensive bibliography (a reading list)</li>
</ul>

<h5 id="fn-en-block" class="docs" style="font-size: 90%; margin-top: .25em;">Refer block for footnotes/endnotes</h5>

<p style="margin-top: .5em;">
If you want footnote or endnote references, place this block at
the <i>top</i> of your mom file.
</p>

<div id="refer-block1" class="examples" style="margin-top: -.5em;">
<div class="examples-container" style="padding-bottom: 1em;">

<p style="margin-top: .5em; font-size: 95%; line-height: 120%;">
<kbd>&lt;full&nbsp;path&nbsp;to&nbsp;the&nbsp;database&gt;</kbd>

</p>

<h5 id="in-text-block" class="docs" style="font-size: 90%; margin-top: .25em;">Refer block for parenthetical insertions into running text</h5>

<p style="margin-top: .5em;">
If you want short, parenthetical insertions into running text,
referring to works cited in a bibliography, place this block at
the <i>top</i> of your mom file.
</p>

<div id="refer-block2" class="examples" style="margin-top: -.5em;">

</p>

<h5 id="bibliography-block" class="docs" style="font-size: 90%; margin-top: .25em;">Refer block for comprehensive bibliographies</h5>

<p style="margin-top: .5em;">
If you want to output an entire <kbd>refer</kbd> database, or
generate a comprehensive bibliography (a reading list) from a
database, place this block at the <i>bottom</i> of your mom file,
either prior to or immediately after invoking
<a href="#bibliography">BIBLIOGRAPHY</a>.

<kbd>/home/user/refer/my-database</kbd>.
</p>

<h4 id="placement-ref" class="docs">3. Tell mom where you want your references</h4>

<p>
If you want references in footnotes, issue the instruction
<br/>
<span class="pre-in-pp">
  .FOOTNOTE_REFS
</span>
anywhere before the first citation in your file.  Footnote markers
will be inserted into the text, and the bibliographic information
for the citation will appear as a footnote.
</p>

<p>
If you want references in endnotes, issue the instruction
<br/>
<span class="pre-in-pp">
  .ENDNOTE_REFS
</span>
anywhere before the first citation in your file.  Endnote markers
will be inserted into the text, and the bibliographic information
for the citation will appear as an endnote entry.
</p>

<p>
Note that if you want references parenthetically inserted
into running text, referring to entries in a works-cited list
(bibliography) that <kbd>mom</kbd> and <kbd>refer</kbd> assemble
automatically, no special instructions are required.  See
<a href="#bibliography-from-embedded">Generating a bibliography from parenthetical insertions</a>
for how to output the collected references.
</p>

<p>
For outputting an entire <kbd>refer</kbd> database, or
generating a comprehensive reading list from a database, see the
macro
<a href="#bibliography">BIBLIOGRAPHY</a>.
</p>

<h4 id="accessing-ref" class="docs">4. Accessing references in the database</h4>

<p>
References are accessed by putting keywords from the desired database
record between two special <kbd>refer</kbd> commands:
<br/>
<span class="pre-in-pp">
  .[
</span>
and
<br/>
<span class="pre-in-pp">
  .]
</span>
Keywords are any word, or set of words, that identify a database
record unambiguously.  Thus, if you have only one database record for
the author Ray Bradbury, 
<br/>
<span class="pre-in-pp">
  .[
  bradbury
  .]
</span>
is sufficient.  However, if your database contains several records
for books by Bradbury, say, <i>Fahrenheit 451</i> and <i>The
Martian Chronicles</i>,
&#8220;<kbd>bradbury&nbsp;451</kbd>&#8221; and
&#8220;<kbd>bradbury&nbsp;martian</kbd>&#8221; would identify the two records unambiguously.
</p>

<p>
A special database field identifier, <kbd>%K</kbd>, lets you create
unique keywords for database records to help clear up any ambiguity.
</p>

<p>
Notice that you don&#8217;t have to worry about capitalization when
entering keywords.
</p>

<h4 id="fn-en-recipe" class="docs">5. Entering footnote/endnote references</h4> 

<p>
Depending on which you have issued, a
<kbd><a href="#footnote-refs">.FOOTNOTE_REFS</a></kbd>
or an
<kbd><a href="#endnote-refs">.ENDNOTE_REFS</a></kbd>
command, entering references is done like this:
<br/>
<span class="pre-in-pp">
  .REF
  .[
  keyword(s)
  .]
  .REF
</span>
If FOOTNOTE_REFS is in effect, the reference between the first
and second <kbd>.REF</kbd> will be treated as a footnote.  If
ENDNOTE_REFS, it will be treated as an endnote.  Endnote references
must be explicitly output with
<a href="docelement.html#ENDNOTES">ENDNOTES</a>
at the end of your file, before
<a href="tables-of-contents.html#TOC">TOC</a>.
</p>

<div class="box-important">
<p class="tip">
<span class="important">Important:</span>
REF behaves identically to
<a href="docelement.html#footnote">FOOTNOTE</a>
and
<a href="docelement.html#endnote">ENDNOTE</a>
with respect to the use of the <kbd>\c</kbd> inline escape.  Please
read the
<a href="docelement.html#footnote-note">HYPER IMPORTANT NOTE</a>
found in the document entry for FOOTNOTE (which also applies to
ENDNOTE).
</p>
</div>

<h4 id="parenthetical-insertions" class="docs">6. Parenthetical insertions</h4>

<p>
See
<a href="#parenthetical">Inserting parenthetical references into
text</a>.
</p>

<h4 id="bibliography-from-embedded" class="docs">7. Generating a bibliography from parenthetical insertions</h4>

<p>
To generate a bibliography from works cited by parenthetical
insertions in the text, put this at the end of your document, before
<kbd><a href="tables-of-contest.html#TOC">.TOC</a></kbd>.
<br/>
<span class="pre-in-pp">
  .BIBLIOGRAPHY
  .[
  $LIST$
  .]
  .BIBLIOGRAPHY OFF
</span>
</p>

<h4 id="bibliography-recipe" class="docs">8. Generating a comprehensive bibliography</h4>

<p>
You can also generate a comprehensive bibliography, which is to say a
bibliography containing more works than are actually cited (a
&#8220;reading list&#8221;), by placing references between
<kbd><a href="#bibliography">.BIBLIOGRAPHY</a></kbd>
and
<kbd><a href="#bibliography">.BIBLIOGRAPHY&nbsp;OFF</a></kbd>.
Once you have input the desired references, insert
<br/>
<span class="pre-in-pp">
  .[
  $LIST$
  .]
</span>
and follow it with <kbd>.BIBLIOGRAPHY&nbsp;OFF</kbd>.  Study the
example below if you&#8217;re having trouble visualizing this.
</p>

<div id="example-bibliography" class="examples" style="margin-top: -.5em;">Example bibliography</div>

<p>
Alternatively, you can output an entire database as a

<kbd><a href="tables-of-contest.html#TOC">.TOC</a></kbd>.
<br/>
<span class="pre-in-pp">

<h4 id="invoking-ref" class="docs">9. Invoking groff with mom and refer</h4>

<p>
So, now you&#8217;ve got a document formatted properly to use
references processed with <kbd>refer</kbd>, what do you do to output
the document?
</p>

<p>
It&#8217;s simple.  Instead of invoking groff with just the
<kbd>-mom</kbd> option, as explained
<a href="using.html#using-saving">here</a>,
invoke groff with the <kbd>-R</kbd> option as well, like this:
<br/>
<span class="pre-in-pp">
  groff -R -mom &lt;filename&gt; ...
</span>
</p>
</div>

<div class="rule-medium" style="margin-top: 1em;"><hr/></div>

<h2 id="mla" class="docs">MLA (Modern Language Association) style</h2>

<h3 id="ref-styles" class="docs">Types of references (endnote, footnote, or embedded in text)</h3>

<p>
MLA allows for three types of references, or referencing styles:
</p>
<ul style="margin-top: -.5em;">
  <li>short, parenthetical references in the text, linked to a
      works-cited list (bibliography) at the end of the document</li>
  <li>footnote references</li>
  <li>endnote references</li>
</ul>

<p style="margin-top: -.5em;">
There are significant differences between the way footnote/endnote
references should be formatted, and the formatting style of
bibliographies.  One example is that footnote/endnote references
should have their first lines indented, whereas bibliographic
references should have their second lines indented.  Fortunately,
with mom, there&#8217;s no need to concern yourself with the differences;
they&#8217;re taken care of automatically.
</p>

<p>
In terms of inserting references into your documents,
footnote/endnote references are input in a manner similar to
entering any other kind of
<a href="docelement.html#footnote-into">footnote</a>
or
<a href="docelement.html#endnote-into">endnote</a>.
Parenthetical references, however, need to be handled differently.
See the next section.
</p>

<h3 id="parenthetical" class="docs">Inserting parenthetical references into the text</h3>

<p>
MLA style prefers restricting the information in parenthetical
references to the barest minimum needed to identify works
in the works-cited list (the bibliography).  Typically, a
parenthetical insertion is just the author&#8217;s last name
followed by the page number of the cited work (if only one work by
that author is cited), or by the author, a shortened title of the
work, and the page number (if more than one work is cited).
</p>

<p>
This necessitates a slightly fiddly way of entering parenthetical
references, though not by any means difficult or hard to make sense
of.
</p>

<p>
The <kbd>refer</kbd> block suggested
<a href="#refer-block2">here</a>
for parenthetical references prints only the author&#8217;s
last name from the database record identified by your keywords
(the <kbd>label</kbd> command), surrounded by parentheses (the
<kbd>bracket-label</kbd> command).  Therefore, assuming you are
citing Ray Bradbury&#8217;s <i>The Martian Chronicles</i>, and it is
the only work by Bradbury mentioned in the text,
<br/>
<span class="pre-in-pp">
  ...end of sentence.
  .[
  martian chronicles
  .]
  A new sentence...
</span>
will insert &#8220;<span style="font-family: times; font-size: 105%; font-weight: bold">...end of sentence (Bradbury). A new sentence...</span>&#8221; into the text.
<i>The Martian Chronicles</i> will be added
to the works-cited list generated at the end of the document if it
is not already present as the result of an earlier reference.
</p>

<p>
If you need a page number to identify where in <i>The Martian
Chronicles</i> to find a specific quote
<br/>
<span class="pre-in-pp">
  "...aluminum roaches and iron crickets."
  .[
  [ martian chronicles
  .] 168)
  A new sentence...
</span>
results in &#8220;<span style="font-family: times; font-size: 105%; font-weight: bold">&#8220;...aluminum roaches and iron crickets.&#8221; (Bradbury 168)  A new sentence...</span>&#8221;
(which is excruciatingly correct MLA style).  The
&#8220;<kbd>[</kbd>&#8221; before <kbd>martian&nbsp;chronicles</kbd> tells
refer to print the opening parenthesis; any text immediately
following the &#8220;<kbd>.]</kbd>&#8221;, including spaces,
<i>replaces</i> the closing parenthesis.  (Notice that you have to
add the closing parenthesis yourself after the page number.)
</p>

<p>
If your document cites more than one work by Bradbury and you need
a title and page number in addition to the author's name in the
inline reference,
<br/>
<span class="pre-in-pp">
  "...aluminum roaches and iron crickets."
  .[
  [ bradbury martian
  .], \fIChronicles\fP 168)
  A new sentence...
</span>
will produce &#8220;<span style="font-family: times; font-size: 105%; font-weight: bold">&#8220;...aluminum roaches and iron crickets.&#8221; (Bradbury, <i>Chronicles</i> 168) A new sentence...</span>&#8221;.

<p>
The <kbd>label</kbd> and <kbd>bracket-label</kbd> commands in
the refer block allow you to customize what information goes
into parenthetical references, and how they should be formatted.
<kbd>label</kbd> dictates which fields from the database record

<h2 id="database" class="docs">The refer database</h2>

<h3 id="database-intro" class="docs">Introduction</h3>

<p style="margin-top: .5em;">
The heart and soul of <kbd>refer</kbd> is the bibliographic
database.  Knowing how to create records (ie. the entries for works
cited in a document) is largely a question matching data (author,
title, publisher, etc) with the correct field identifier.  For
example, if you&#8217;re citing from a scholarly journal, you need to know
that <kbd>%J</kbd> is the field identifier for journal names and
<kbd>%N</kbd> is the field identifier for the journal number.  Use
the
<a href="#fields-quick">Quick list of field identifiers</a>
as your guide.
</p>

<h3 id="database-rules" class="docs">The rules</h3>

<p style="margin-top: .5em;">
Entering the data correctly is also important.  Fortunately, there
are very few rules, and those there are make sense.  In a nutshell:
</p>
<ul style="margin-top: -.5em;">
  <li>enter the data in each field in natural order; author John Smith is
      &#8220;John Smith&#8221;, editor Jane Doe is &#8220;Jane Doe&#8221;</li>
  <li>capitalize all proper nouns and words in titles as you expect
      to see them; otherwise, use lowercase</li>
  <li>use no terminating punctuation unless required; typically,
      required punctuation is the period after a shortform
      (&#8220;ed.&#8221; or &#8220;eds.&#8221;, &#8220;Jr.&#8221;,
      etc) or a question mark or exclamation mark at the end of a
      title</li>
  <li>if part of a field needs to be set off in single-quotes, use
      <kbd>\[oq]</kbd> and <kbd>\[cq]</kbd> (openquote, closequote) rather than the
      single-quote (or apostrophe) character on your keyboard</li>
  <li>if part of a field needs to be forced into italics, use the
      escapes <kbd>\*[IT]</kbd> and <kbd>\*[PREV]</kbd>; if the italicized
      portion concludes the field, omit <kbd>\*[PREV]</kbd></li>
  <li>if you require characters with accents, ligatures or special
      symbols, use groff&#8217;s &#8220;named&#8221; glyphs (e.g.,
      <kbd>\['e]</kbd> for <kbd>é</kbd>); a full list can be found in
      <kbd>man groff_char</kbd></li>
</ul>

<h3 id="fields-specifics" class="docs">Field identifiers: specifics, usage and examples</h3>

<h4 id="A" class="docs fields">%A &ndash; author field</h4>

<p>
For multiple authors, enter each in a separate <kbd>%A</kbd>
field in the order in which they should appear.  If the author on
the title page is the editor (say, a book of short stories edited by
Ray Bradbury), add <kbd>, ed.</kbd> to the end of the
<kbd>%A</kbd> field, like this:
<br/>
<span class="pre-in-pp">
  %A Ray Bradbury, ed.
</span>
Do not use the <kbd>%E</kbd> field in these instances.  If the work
has several such editors, enter each in a separate <kbd>%A</kbd>
field, as for multiple authors, and add <kbd>, eds.</kbd> to the
last one, like this:
<br/>
<span class="pre-in-pp">
  %A Jane Dearborne
  %A Bill Parsons, eds.
</span>
</p>

<h4 id="Q" class="docs fields">%Q &ndash; exceptional entries</h4>

<p>
Sometimes, a work has no author or title information, for example a
book review in a newspaper.  In such cases, use <kbd>%Q</kbd>, like
this:
<br/>
<span class="pre-in-pp">
  %Q Rev. of \*[IT]Mean Streets Omnibus\*[PREV], ed. Raymond Hammett
  %M Times Literary Supplement
  %D 7 July 1972
</span>
</p>

<h4 id="m" class="docs fields">%m &ndash; multiple authors (et al.)</h4>

<p>
Whenever it&#8217;s desirable to abbreviate a list of authors with
&#8220;et al.&#8221; enter it in the <kbd>%m field</kbd>, like this:
<br/>
<span class="pre-in-pp">
  %A Paul Lauter
  %A Doug Scofield
  %m et al.
</span>
</p>

<h4 id="i" class="docs fields">%i &ndash; idem</h4>

<p>
Whenever there are several works by the same author, fill out the
<kbd>%A</kbd> field with the author&#8217;s name and follow it with the
<kbd>%i idem</kbd>, like this:
<br/>
<span class="pre-in-pp">
  %A Jonathon Schmidt
  %i idem
</span>
Per MLA style, the author&#8217;s name will be replaced by a long dash.
</p>

<p>
If it&#8217;s necessary to state the role the author served (say,
editor or translator), fill out the <kbd>%i</kbd> field with the
information minus <kbd>idem</kbd>, like this:
<br/>
<span class="pre-in-pp">
  %A Ray Bradbury
  %i ed.
  %T Timeless Stories for Today and Tomorrow
</span>
</p>

<h4 id="p" class="docs fields">%p &ndash; post-author information</h4>

<p>
When citing from a preface, foreword, introduction, afterword or
appendix, MLA requires that the information come between the
author&#8217;s name and the work&#8217;s title, like this:
<br/>
<span class="pre-in-pp">
  %A Martin Packham, Jr.
  %p appendix
  %T Why the West was Won
</span>
Do not capitalize the first word in the <kbd>%p</kbd> field unless
it is a proper noun.
</p>

<h4 id="q" class="docs fields">%q &ndash; force title into double-quotes</h4>

<p>
Occasionally, you may not be able to use <kbd>%T</kbd> for the
title because doing so will cause it to come out in italics when
double-quotes are called for.  An example of this is when citing
from a dissertation.  Use <kbd>%q</kbd> to get around the problem,
like this:
<br/>
<span class="pre-in-pp">
  %A Carol Sakala
  %q Maternity Care Policy in the United States
  %O diss., Boston U, 1993
</span>
</p>

<h4 id="E" class="docs fields">%E &ndash; editor</h4>

<p>
Use this only if the author and the editor are not one in the same,
e.g.,
<br/>
<span class="pre-in-pp">
  %A Geoffrey Chaucer
  %T The Works of Geoffrey Chaucer
  %E F. W. Robinson
</span>
</p>

<h4 id="l" class="docs fields">%l &ndash; translator</h4>

<p>
If there is more than one translator, enter all the names, with
appropriate conjunctions and punctuation, like this:
<br/>
<span class="pre-in-pp">
  %A Feodor Dostoevsky
  %T Crime and Punishment
  %l Jessie Coulson, Marjorie Benton, and George Bigian
</span>
</p>

<h4 id="O" class="docs fields">%O &ndash; other</h4>

<p>
Occasionally, MLA requires additional information after the title
but before the publication data (city/publisher/date), for instance,
the number of volumes in a series, or the fact that the work cited
is a dissertation.  Here are two examples:
<br/>
<span class="pre-in-pp">
  %A Arthur M. Schlesinger
  %T History of U.S. Political Parties
  %O 4 vols.
  %C New York
  %I Chelsea
  %D 1973

  %A Carol Sakala
  %q Maternity Care Policy in the United States
  %O diss., Boston U, 1993
</span>
Do not capitalize the first word of the <kbd>%O</kbd> field unless
it is a proper noun.
</p>

<p>
Generally, consider <kbd>%O</kbd> a catch-all for information that
does not match the criterion of any existing field identifier.
</p>

<h4 id="C" class="docs fields">%C &ndash; city</h4>

<p>
Normally, <kbd>%C</kbd> takes the name of the city of publication,
and that&#8217;s all.  In the case of a republished book, if new material
has been added, put such information in the <kbd>%C</kbd>
field, like this:
<br/>
<span class="pre-in-pp">
  %A Theodore Dreiser
  %T Sister Carrie
  %d 1900
  %C Introd. E. L. Doctorow, New York
</span>
</p>

<h4 id="d" class="docs fields">%d &ndash; original date of publication</h4>

<p>
Normally, all that is required in the <kbd>%d</kbd> field is the
original date of publication.  However, if supplementary original
publication data is desired, include it in the field, like this:
<br/>
<span class="pre-in-pp">
  %A Kazuo Ishiguro
  %T The Remains of the Day
  %d London: Faber, 1989
  %C New York
  %I Knopf
  %D 1990
</span>
</p>

<h4 id="K" class="docs fields">%K &ndash; keywords</h4>

<p>
<kbd>Refer</kbd> hates ambiguity, and complains when encountering
it.  Ambiguities result from the duplication of any word in more
than one database record when that word is used to identify a
reference in your input file.  Use <kbd>%K</kbd> to create unique
keywords found nowhere else in the database.
</p>

<p>
Imagine, for example, that your database contains records for
Ray Bradbury&#8217;s <i>The Illustrated Man</i>, another record for
<i>The Illustrated Bradbury</i> and a third for <i>Bradbury,
Illustrated</i>.  <kbd>%K</kbd> can be used to clear up any
ambiguities by assigning a unique word to each record, for example
<kbd>%K ill-man</kbd> for the first, <kbd>%K ill-brad</kbd> for the
second, and <kbd>%K brad-ill</kbd> for the third.
</p>

<h4 id="P" class="docs fields">%P &ndash; pages</h4>

<p>
When citing page numbers, which is often the case with footnotes
and endnotes, it is not necessary to put the numbers in the database
records.  The <kbd>%P</kbd> field can be added underneath the
keyword(s) in the <kbd>.[</kbd> / <kbd>.]</kbd> entries in your
input file, allowing you to recycle database records.  For example,
<br/>
<span class="pre-in-pp">
  %A Frye
  %T Anatomy
  %K frye-anat
</span>
could be your short record for Northrop Frye&#8217;s <i>The Anatomy of
Criticism</i>.  Any time you wanted to cite a particular page or
range of pages from that work in a footnote or endnote, you can
put
<br/>
<span class="pre-in-pp">
  .REF
  .[
  frye-anat
  %P 67-8
  .]
  .REF
</span>
in your input file, and have it show up with the correct page(s).
</p>

<h4 id="n" class="docs fields">%n &ndash; annotations</h4>

<p>
Annotations come at the very end of references.  Capitalize all
words that require it, including, for bibliographic references (but not
for footnotes/endnotes) the first.

Macro: <b>REF</b>
</div>

<p>
The macro REF tells mom that what follows is
<kbd>refer</kbd>-specific, a keyword-identified reference to a
<kbd>refer</kbd> database record.  Depending on whether you&#8217;ve issued
a
<kbd><a href="#footnote-refs">.FOOTNOTE_REFS</a></kbd>
or
<kbd><a href="#endnote-refs">.ENDNOTE_REFS</a></kbd>
instruction, the reference will be formatted and placed in a
footnote, or collected for output in the endnotes.  Parenthetical
insertion of references into the text do not require
<kbd>.REF</kbd> (see
<a href="#parenthetical">Inserting parenthetical references into the text</a>.)
</p>

<p>
Before you use REF, you must create a <kbd>refer</kbd> block
containing <kbd>refer</kbd> commands (see
<a href="#rcommands-ref">Required refer commands</a>
in the tutorial, above).
</p>

<p>
REF usage always looks like this:
<br/>
<span class="pre-in-pp">
  .REF
  .[
  keyword(s)
  .]
  .REF
</span>
Notice that REF &#8220;brackets&#8221; the <kbd>refer</kbd> instructions,
and never takes an argument.
</p>

<p>
What REF really is is a convenience.  One could, for example, put a
reference in a footnote by doing
<br/>
<span class="pre-in-pp">
  .FOOTNOTE
  .[
  keyword(s)
  .]
  .FOOTNOTE OFF
</span>
However, if you have a lot of references going into footnotes (or
endnotes), it&#8217;s much shorter to type <kbd>.REF/.REF</kbd>
than <kbd>.FOOTNOTE/.FOOTNOTE OFF</kbd>.  It also helps you
distinguish&mdash;visually, in your input file&mdash;between
footnotes (or endnotes) which are references, and footnotes (or
endnotes) which are explanatory, or expand on the text.
</p>

<div class="box-tip">
<p class="tip-top">
<span class="note">Note:</span>
If you&#8217;re using REF to put references in footnotes and your
footnotes need to be indented, you may (indeed, should) pass REF the
same arguments used to indent footnotes.  See

</p>

<p>
MLA-style requires that footnote or endnote references should
have their first lines indented, whereas bibliographic references
should have their second and subsequent lines indented.  Thus, if
you invoke INDENT_REFS with a first argument of <kbd>FOOTNOTE</kbd>
or <kbd>ENDNOTE</kbd>, the value you give to
<kbd>&lt;indent&gt;</kbd> sets the indent of the first line for
those types of references; if you invoke it with <kbd>BIBLIO</kbd>,
the value you give <kbd>&lt;indent&gt;</kbd> sets the indent of
second and subsequent lines in bibliographies.
</p>

<p>
By default, the indent for all three types of references is 1/2-inch
for
<a href="docprocessing.html#printstyle">PRINTSTYLE <kbd>TYPEWRITE</kbd></a>
and 2
<a href="definitions.html#em">ems</a>
for
<a href="docprocessing.html#printstyle">PRINTSTYLE <kbd>TYPESET</kbd></a>.
</p>

<p>
If you&#8217;d like to change the indent for footnote, endnote or
bibliography references, just invoke <kbd>.INDENT_REFS</kbd> with
a first argument saying which one you want the indent changed for, and
a second argument saying what you&#8217;d like the indent to be.
For example, if you want the second-line indent of references on a
bibliography page to be 3
<a href="definitions.html#picas-points">picas</a>,
<br/>
<span class="pre-in-pp">
  .INDENT_REFS BIBLIO 3P

into endnotes (with
<a href="#endnote-refs">ENDNOTE_REFS</a>),
you will almost certainly want to adjust the second-line indent for
references in endnotes, owing to the way mom formats line-numbered
endnotes.  Study the output of such documents to see whether an
indent adjustment is required.

<p>
The same advice applies to references in endnotes when you have enabled

best.

left-aligned endnote numbers is a no-win situation, and so is best
avoided.  Wherever you set the indent, you&#8217;ll end up with the

Macro: <b>HYPHENATE_REFS</b> <kbd class="macro-args">&lt;toggle&gt;</kbd>
</div>

<p>
If you have hyphenation turned on for a document (see
<a href="typesetting.html#hy">HY</a>),
and in most cases you probably do, mom will hyphenate references
bracketed by the
<a href="#ref">REF</a>
macro.  Since references typically contain quite a lot of proper
names, which shouldn&#8217;t be hyphenated, you may want to disable
hyphenation for references.
</p>

<p>
HYPHENATE_REFS is a toggle macro; invoking it by itself will turn
automatic hyphenation of REF-bracketed references on (the default).
Invoking it with any other argument (<kbd>OFF, NO, X</kbd>, etc.)
will disable automatic hyphenation for references bracketed by REF.
</p>

<p>
An alternative to turning reference hyphenation off is to prepend
to selected proper names in your <kbd>refer</kbd> database
the groff
<a href="definitions.html#discretionaryhyphen">discretionary hyphen</a>
character, <kbd>\%</kbd>.  (See
<a href="#ref-disc-hy">here</a>
in the tutorial for an example.)

<div class="box-tip">
<p class="tip">
<span class="note">Note:</span>
References embedded in the body of a document are considered part of
<a href="definitions.html#running">running text</a>,
and are hyphenated (or not) according to whether hyphenation is
turned on or off for running text.  Therefore, if you want to
disable hyphenation for such references, you must do so temporarily,
with
<a href="typesetting.html#hy">HY</a>,
like this:
<br/>
<span class="pre-in-pp">
  .HY OFF

<p>
To append a bibliography to your document, whether of references
inserted parenthetically into text or a comprehensive reading list
derived from a large <kbd>refer</kbd> database, all you need
do is invoke <kbd>.BIBLIOGRAPHY</kbd>. <kbd>.BIBLIOGRAPHY</kbd>
breaks to a new page, prints the title (BIBLIOGRAPHY by default, but
that can be changed), and awaits <kbd>refer</kbd> instructions.  How
to create bibliographies is covered in the tutorial section,

<a href="#bibliography-recipe">Generating a comprehensive bibliography</a>.

<p>
Mom offers two styles of bibliography output: plain, or numbered
list style.  With the argument, <kbd>PLAIN</kbd>, bibliography entries are output
with no enumerators.  With the argument, <kbd>LIST</kbd>, each entry is numbered.
</p>

<p>
The two optional arguments, <kbd>&lt;list&nbsp;separator&gt;</kbd>

</p>

<p>
You may enter the BIBLIOGRAPHY_TYPE either before or after

<div class="box-macro-args">
Macro: <b>BIBLIOGRAPHY_PT_SIZE</b> <kbd class="macro-args">&lt;base type size of bibliography&gt;</kbd>
</div>

<p>
Unlike most other control macros that deal with size of document
elements, BIBLIOGRAPHY_PT_SIZE takes as its argument an absolute
value, relative to nothing.  Therefore, the argument represents the
size of bibliography type in
<a href="definitions.html#picaspoints">points</a>,
unless you append an alternative
<a href="definitions.html#unitofmeasure">unit of measure</a>.
For example,
<br/>
<span class="pre-in-pp">
  .BIBLIOGRAPHY_PT_SIZE 12
</span>
sets the base point size of type on the bibliography page to 12
points, whereas
<br/>
<span class="pre-in-pp">
  .BIBLIOGRAPHY_PT_SIZE .6i
</span>
sets the base point size of type on the bibliography page to 1/6 of an
inch.
</p>

<p>
The type size set with BIBLIOGRAPHY_PT_SIZE is the size of type used
for the text of the bibliographies, and forms the basis from which
the point size of other bibliography page elements is calculated.
</p>

<p>
The default for
<a href="docprocessing.html#printstyle">PRINTSTYLE <kbd>TYPESET</kbd></a>
is 12.5 points (the same default size used in the body of the
document).

<p>
Unlike most other control macros that deal with leading of document

relative to nothing.  Therefore, the argument represents the
<a href="definitions.html#leading">leading</a>

<a href="definitions.html#picaspoints">points</a>
unless you append an alternative
<a href="definitions.html#unitofmeasure">unit of measure</a>.
For example,

<span class="pre-in-pp">
  .BIBLIOGRAPHY_LEAD 14
</span>
sets the base leading of type on the bibliography page to 14
points, whereas
<br/>
<span class="pre-in-pp">
  .BIBLIOGRAPHY_LEAD .5i
</span>
sets the base leading of type on the bibliography page to 1/2 inch.
</p>

<p>
If you want the leading of bibliographies adjusted to fill the page,
pass BIBLIOGRAPHY_LEAD the optional argument,
<kbd>ADJUST</kbd>.  (See
<a href="docprocessing.html#doc-lead-adjust">DOC_LEAD_ADJUST</a>
for an explanation of leading adjustment.)
</p>

<p>
The default for
<a href="docprocessing.html#printstyle">PRINTSTYLE <kbd>TYPESET</kbd></a>
is the prevailing document lead (16 by default), adjusted.
</p>

<div class="box-tip">

<span style="font-style: normal"><kbd>&lt;underscore weight&gt;</kbd></span>
must not have the
<a href="definitions.html#unitofmeasure">unit of measure</a>,
<span style="font-style: normal;"><kbd>p</kbd></span>, appended to it
</p>

<p>
Invoked without an argument,
<kbd>.BIBLIOGRAPHY_STRING_UNDERSCORE</kbd> will place a single rule
underneath the bibliography&#8217;s first-page title.  Invoked with the
argument, <kbd>DOUBLE</kbd>, BIBLIOGRAPHY_STRING_UNDERSCORE will
double-underscore the title.  Invoked with any other non-numeric
argument, (e.g., <kbd>OFF, NO, X</kbd>, etc.) the macro disables
underlining of the title.
</p>

<p>
In addition, you can use BIBLIOGRAPHY_STRING_UNDERSCORE to control
the weight of the underscore rule(s), the gap between the title and
the underscore, and, in the case of double-underscores, the distance
between the two rules.
</p>

<p>
Some examples:
<br/>
<span class="pre-in-pp">
  .BIBLIOGRAPHY_STRING_UNDERLINE 1
      - turn underlining on; set the rule weight to 1 point

  .BIBLIOGRAPHY_STRING_UNDERLINE 1 3p
      - turn underlining on; set the rule weight to 1 point; set
        the gap between the string and the underline to 3 points
  
  .BIBLIOGRAPHY_STRING_UNDERLINE DOUBLE .75 3p
      - turn double-underlining on; set the rule weight to 3/4 of
        a point; set the gap between the string and the upper
        underline to 3 points; leave the gap between the upper
        and the lower underline at the default
  
  .BIBLIOGRAPHY_STRING_UNDERLINE DOUBLE 1.5 1.5p 1.5p
      - turn double-underlining on; set the rule weight to 1-1/2
        points; set the gap between the string and the upper
        underline to 1-1/2 points; set the gap between the upper
        and the lower underline to 1-1/2 points
</span>
Note, from the above, that in all instances, underscoring (single or
double) is enabled whenever BIBLIOGRAPHY_STRING_UNDERSCORE is used
in this way.
</p>

<p>
By default, mom double-underscores the title if your
<a href="docprocessing.html#printstyle">PRINTSTYLE</a>
is <kbd>TYPEWRITE</kbd>.

<!-- -BIBLIO_STRING_CAPS- -->

<h5 id="biblio-string-caps" class="docs" style="margin-top: -.5em; margin-bottom: .5em; margin-left: .5em;">&bull;&nbsp;Title string capitalization</h5>

<div class="box-macro-args">
Macro: <b>BIBLIOGRAPHY_STRING_CAPS</b> <kbd class="macro-args">toggle</kbd>
</div>

<p>
Invoked by itself, <kbd>.BIBLIOGRAPHY_STRING_CAPS</kbd> will
automatically capitalize the bibliography first-page title.  Invoked
with any other argument, the macro disables automatic capitalization
of the title.
</p>

<p>
If you&#8217;re generating a table of contents, you may want the
bibliography first-page title to be in caps, but the toc entry in
caps/lower case.  If the argument to
<kbd><a href="#bibliography-string">BIBLIOGRAPHY_STRING</a></kbd>
is in caps/lower case and BIBLIOGRAPHY_STRING_CAPS is
on, this is exactly what will happen.
</p>

<p>
Mom&#8217;s default is to capitalize the bibliography first-page
title.
